Adjustable Throttle and Brake Pedal
If your vehicle has this feature, you can change
the position of the throttle and brake pedals.
This feature is designed for shorter drivers, since
the pedals cannot move farther away from the
standard position, but can move toward the driver
for better pedal reach.
The switch used to
adjust the pedals is
located on the center
console below the
climate control system.Press the arrow at the bottom of the switch to
move the pedals closer to your body. Press
the arrow at the top of the switch to move the
pedals away from your body.
No adjustment to the pedals can be made when
the vehicle is in REVERSE (R) or while using
the cruise control.
Your vehicle has a memory function which allows
pedal settings to be saved and recalled. See
Memory Seat, Mirrors, and Pedals on page 12for
more information.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):Press this button
to turn on the rear window defogger. It will
automatically turn off several minutes after it
has been activated. The defogger can also be
turned off by pressing the button again or by
turning off the engine. Do not drive the vehicle until
all the windows are clear.
If your vehicle has heated outside rearview
mirrors, the mirrors will heat to help clear fog or
frost from the surface of the mirror when the
rear window defog button is pressed.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Use the air outlets located in the center and on
the side of your instrument panel to direct
the airow.
Operation Tips

Keep the hood and front air inlets free of ice,
snow, or any other obstruction (such as
leaves). The heater and defroster will work
better, reducing the chance of fogging
the inside of your windows.
When you enter a vehicle in cold weather, set
the fan speed to maximum airow for a few
moments before driving. This helps clear
the intake ducts of snow and moisture, and
reduces the chance of fogging the inside
of your window.
Keep the air path under the front seats clear
of objects. This helps air to circulate
throughout your vehicle.

To listen to a device through the rear auxiliary
input over the speakers, cycle the DVD/CD Aux
button on the radio faceplate until “Rear Aux Input”
is displayed on the radio. The RSA or DVD
Screen must be on in order for the radio to source
to rear auxiliary.
O(Power/Volume):Turn this knob clockwise or
counterclockwise to increase or decrease the
volume of the portable player. You may need to do
additional volume adjustments from the portable
device if the volume does not go loud or soft
enough.
BAND:Press this button to listen to the radio
when a portable audio device is playing. The
portable audio device will continue playing, so you
may want to stop it or power it off.DVD/CD AUX (CD/Auxiliary):Press this button to
cycle through DVD, CD, or Auxiliary when
listening to the radio. The DVD/CD text label and
a message showing track or chapter number
will appear on display when a disc is in either slot.
Press this button again and the system will
automatically search for an auxiliary input device,
such as a portable audio player. If a portable
audio player is not connected, “no aux input
device” will be displayed. If a disc is in both the
DVD slot and the CD slot the DVD/CD AUX button
will cycle between the two sources and not
indicate “no aux input device”. If a front auxiliary
device is connected, the DVD/CD AUX button
will cycle through all available options, such as:
DVD slot, CD slot, Front AUX, and Rear AUX
(if available). See “Using the Auxiliary Input
Jack(s)” later in this section, orRear Seat
Entertainment System on page 321, “Audio/Video
(A/V) Jacks” for more information.

Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been
preset at the factory and should need no further
adjustment.
However, if the vehicle is damaged in an accident,
the aim of the headlamps may be affected and
adjustment may be necessary.
If oncoming vehicles ash their high beams at
you, this may mean the vertical aim of your
headlamps needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be
adjusted. It is possible however, to re-aim the
headlamps as described in the following procedure.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall.
The vehicle must have all four tires on a level
surface which is level all the way to the wall.
The vehicle should be placed so it is
perpendicular to the wall.
The vehicle should not have any snow, ice,
or mud on it.
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being performed.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) sitting on the driver’s seat.
Tires should be properly inated.
The spare tire is in its proper location in the
vehicle.
Headlamp aiming is done with the vehicle’s
low-beam headlamps. The high-beam headlamps
will be correctly aimed if the low-beam headlamps
are aimed properly.
